Solvent Resistance of Cured Films
[Test Method]
After cured material was immersed into the individual solvent, the change in material appearance between before and after immersion was observed.

Types of Coatalent Series Coating Solutions
-
Non-catalyst type
High temperature baking (e.g., baking at 350°C for 1 hr in air) is required for conversion to silica.
This is a basic perhydropolysilazane solution. -
Palladium catalyst type
Since palladium is an inorganic catalyst, the coating quality (elaborateness and strength) is superior to amine catalyst type. So, palladium catalyst type is suitable for the corrosion resistance and scratch resistance.
This solution is brown but thin coating film after applied is transparent.
-
Amine catalyst type
Using this grade, conversion to silica is obtained at 150°C for 1 hr, lower temperature than the palladium type and is also produced at room temperature in approx.
2 weeks. This type is most suitable for the purpose of anti-soiling coating.
